A new synthetic methodology for pyridinic sucrose esters and their antibacterial effects against Gram-positive and Gram-negative strains
(Carbohydrate Research, 2020) [Artigo]Described are the development of a new synthetic method using ultrasonic irradiation and sodium methoxide as catalyst for a series of pyridinic sucrose esters (py-SEs), derived from transesterification of sucrose with ... -
Soaking and ozonolysis pretreatment of sugarcane straw for the production of fermentable sugars
(Industrial Crops and Products, 2020) [Artigo]In the present study, sugarcane straw residue (SCS) is used to generate fermentable sugars. Impregnation in different media and ozonolysis were combined for SCS treatment. The best results were obtained for the basic medium ... -
Antiviral activity of curcumin-nanoemulsion associated with photodynamic therapy in vulvar cell lines transducing different variants of HPV-16
(Artificial Cells, Nanomedicine and Biotechnology, 2020) [Artigo]Vulvar intraepithelial neoplasia (VIN) is associated with human papillomavirus (HPV) infection. Curcumin is a natural bioactive compound with antineoplastic properties. The use of nanoparticles containing curcumin could ... -
Relationship of polymorphism rs3800231 in FOXO3 gene and clinical severity with oxidative stress markers in sickle cell disease
(Meta Gene, 2020) [Artigo]Sickle cell disease (SCD) is a hereditary disease characterized by a clinical course highly variable that is significantly affected by several modifying factors, whose majority still poorly understood. Due to the importance ... -
β-Glucosidase production by Trichoderma reesei and Thermoascus aurantiacus by solid state cultivation and application of enzymatic cocktail for saccharification of sugarcane bagasse
(Biomass Conversion and Biorefinery, 2020) [Artigo]For degradation of sugarcane bagasse (SCB), several enzymes are needed but β-glucosidase is rate limiting in cellulose hydrolysis. Since different microorganisms synthetize characteristic pool of enzymes, mixing extracts ... -
Perinatal exposure to bisphenol A impacts in the mammary gland morphology of adult Mongolian gerbils
(Experimental and Molecular Pathology, 2020) [Artigo]The endocrine disruptive effects caused by bisphenol A (BPA) are well known. Despite this, to date, evaluation of its long term effects is limited, meaning that there is still much to be unveiled in terms of alterations ... -
Stepped vitrification technique for human ovarian tissue cryopreservation
(Scientific Reports, 2019) [Artigo]The advantage of stepped vitrification (SV) is avoiding ice crystal nucleation, while decreasing the toxic effects of high cryoprotectant concentrations. We aimed to test this method for human ovarian tissue cryopreservation. ... -
Impact of perinatal bisphenol A and 17β estradiol exposure: Comparing hormone receptor response
(Ecotoxicology and Environmental Safety, 2020) [Artigo]Hormonal regulation controls mammary gland (MG) development. Therefore some hormone-related factors can disrupt the early phases of MGs development, making the gland more susceptible to long term modifications in its ... -
